Textile machine drafting station has two sets of drafting rollers with adjustable mutual separation

摘要

A spinning machine has a drafting station located between two pairs of drafting rollers whose effective mutual separation is adjustable by deflection (17) of lift/lower roller (19) action. The deflection roller (19) rotation is driven by passage of the fibre band (2) or by motor action. In a further embodiment two belt-linked rollers lift and lower. The twin-roller diameter is less than the diameter of the smallest drafting rollers (3, 4, 5).
